Each mfr. offers their own selection of genuine stones. It is important that you view the stone options for each individual item by clicking on the option boxes located on each individual product page. Often, only one option is available for each birth month. Before ordering, be sure you visit the Product & Stone Information page as indicated on the order page. The stones each individual mfr. offers are generally selected for two reasons... because of pricing (in order to keep pricing more affordable) or because of the settings they offer (some setting's prongs are not long enough to securely hold a cabochon- domed without facets- like Opals or Moonstone) or a sphere like a Cultured Pearl.
